Electronic Journal of Differential Equations, Conference 08 (2002), pp. 1-6. Title: A note on the moving hyperplane method Authors: Celine Azizieh (Univ. Libre de Bruxelles, Bruxelles, Belgique) Luc Lemaire (Univ. Libre de Bruxelles, Bruxelles, Belgique) Abstract: We make precise the domain regularity needed for having the monotonicity and symmetry results recently proved by Damascelli and Pacella on p-Laplace equations. For this purpose, we study the continuity and semicontinuity of some parameters linked with the moving hyperplane method. Published October 21, 2002. Math Subject Classifications: 35J60, 35B99.
